A team of researchers from the Yale school of Forestry and Environmental Studies recently published research indicating scientists have been looking at ‘same-sex sexual behavior‘ (SSB) all wrong.

Rather than being anomalous or abnormal, the researchers suggest that SSB is intrinsic to evolution and that ‘different-sex sexual behavior‘ (DSB) shouldn’t be considered a baseline for sexual activity in the animal kingdom. The reason why? Because the other way doesn’t really makes sense.
